PURPOSE: Apparatus for treating body tissues with electricity or medicaments is provided, which selectively stimulates body tissues or organs and selectively delivers a medicament to a target tissue or organ. CONSTITUTION: In normal use, electricity is applied to the electrodes(2) which causes the electrical stimulation device(1) to generate oscillations in the ultrasonic range. The ceramic motor works according to the second piazo-electric effect, and the reverse, generation of current by vibrating the ceramic is equivalent to the first piazo-electric effect. The frequencies may be varied as specific applications dictate. A wide range of frequencies, e.g., radio frequency(rf) or ultrasound(us), may be utilized depending upon the type and the location of the tissue being treated and the type and amount of tissue through which the high frequency vibrations must pass.
